Letter dated February 5, 2002 from Hamid ‘Ed’ Abbasi, Environmental Engineer, Washington State Department of Ecology (NWRO) to Michael Feldman, Director of Aviation Facilities & Environmental Programs, Seattle-Tacoma International Airport. Ecology denies the Port Of Seattle’s request for an Administrative Order to bypass the industrial waste treatment system at Lagoon #3 under NPDES Permit WA-002465-1,

This 2002 legal declaration by wetland scientist Dyanne Sheldon challenges the adequacy of environmental protections attached to a Washington State Department of Ecology water quality certification related to Sea-Tac Airport expansion. Sheldon argues that the groundwater and wetland performance standards required under the 401 Certification are too vague and scientifically flawed to reliably measure success or failure, citing problems such as undefined 'normal rainfall' baselines and an over-reliance on qualitative wetland plant ratings from the 1980s. The declaration was submitted in support of the Airport Communities Coalition's motion for a stay of the certification before the Washington Pollution Control Hearings Board.

This legal document is part of a Pollution Control Hearings Board case in which the Airport Communities Coalition (ACC) challenged the Port of Seattle and the Washington State Department of Ecology over environmental concerns related to Seattle-Tacoma International Airport. The document lists scientific references and studies relied upon by ACC's expert witnesses, covering topics such as the effects of airport deicing chemicals on water quality, dissolved oxygen levels in receiving streams, toxicity to aquatic life including salmon and trout, and fluoride impacts on fish. The referenced research was used to support ACC's claims about the environmental impact of airport operations on surrounding waterways and ecosystems.

Airport Communities Coalition (ACC) reply brief filed January 29, 2002 in PCHB No. 01-160 before the Pollution Control Hearings Board (PCHB), State of Washington, supporting ACC’s Motion for Summary Judgment on the absence of a water right for the Third Runway Section 401 Water Quality Certification (#1996-4-02325). ACC argues the Port Of Seattle’s Low Flow

Two photographs taken by P. Willing on January 28, 2002, document an absorbent boom placed in a stream below the SDS1 outfall, a pollution-control measure used to contain contaminants. The second photo highlights turbid (murky) effluent visible in the stream, indicating water quality concerns at the site. These images appear to be part of an environmental monitoring or spill-response record associated with drainage infrastructure near Sea-Tac Airport.

This document is an Application for Site Certification for the Wallula Power Project in Washington State, submitted by Wallula Generation LLC to the State of Washington Energy Facility Site Evaluation Council. It details stormwater management plans for the 66-acre project site, including capturing rainfall and routing it through oil/water separators to a detention pond for reuse in the power plant's cooling tower. The application also addresses groundwater rights, noting that captured stormwater would reduce withdrawals from the gravel aquifer and Boise Cascade Corporation fiber farm wells.

This document is an Application for Site Certification for the Wallula Power Project in Washington State, submitted by Wallula Generation LLC to the State of Washington Energy Facility Site Evaluation Council. The application details water management plans for the proposed power plant, including how stormwater runoff from the 66-acre site will be captured, routed through oil/water separators, and reused in the plant's cooling tower basin. The applicant argues that this stormwater reuse strategy will reduce groundwater withdrawals from the local gravel aquifer with no net regional impact on water resources.
